When a tooth is damaged or affected by decay, restoring its function and appearance becomes essential. The two most common restorative treatments are dental crowns and fillings, but they serve different purposes and are suited to different conditions. This guide explores the differences, benefits, and considerations of each to help you make an informed decision.
Understanding Dental Fillings
A dental filling is a restorative treatment used to repair minor damage, such as small to moderate cavities. The procedure involves removing decayed or damaged tooth material and filling the space with a durable material to restore the tooth’s structure.
Types of Filling Materials
- Composite resin: A tooth-coloured material that blends well with natural teeth.
- Amalgam (silver fillings): A durable metal alloy used primarily for back teeth.
- Ceramic: Aesthetic and resistant to staining but can be more costly.
- Gold: A long-lasting option, though less commonly used due to its price and appearance.
When Are Fillings Recommended?
Fillings are generally used for:
- Small to moderate cavities.
- Minor chips or fractures in a tooth.
- Restoring worn-down teeth caused by grinding or acid erosion.
The process is minimally invasive, preserves more of the natural tooth, and is completed in a single visit.
Understanding Dental Crowns
A dental crown is a custom-made cap that covers the entire visible portion of a tooth. It is designed to strengthen, protect, and improve the appearance of teeth that are significantly damaged or weakened.
Types of Crown Materials
- Porcelain or ceramic: Tooth-coloured and highly aesthetic, ideal for front teeth.
- Zirconia: Strong, natural-looking, and suitable for both front and back teeth.
- Porcelain-fused-to-metal (PFM): Combines durability with aesthetics but may show metal along the gumline over time.
- Metal (gold or alloy): Highly durable but less common due to appearance.
When Are Crowns Recommended?
A crown is the preferred option when:
- A tooth has a large cavity that cannot be restored with a filling.
- The tooth is cracked, broken, or significantly worn down.
- A root canal has been performed, requiring reinforcement to protect the tooth.
- The tooth is misshapen or severely discoloured and needs aesthetic improvement.
- A dental bridge needs support from neighbouring teeth.
Crowns offer superior protection and durability, making them ideal for heavily damaged teeth.
Key Differences Between Crowns and Fillings
| Feature | Dental Crown | Dental Filling |
| Purpose | Strengthens and restores a heavily damaged tooth. | Repairs small to moderate cavities. |
| Material Options | Porcelain, zirconia, metal, or PFM. | Composite, amalgam, ceramic, or gold. |
| Tooth Coverage | Covers the entire visible portion of the tooth. | Fills only the damaged or decayed area. |
| Durability | Typically lasts 10–15 years or longer. | Lasts around 5–10 years. |
| Aesthetic Appeal | Mimics the appearance of a natural tooth. | Composite fillings blend well with teeth. |
| Procedure Time | Requires two visits (unless using same-day technology). | Completed in a single appointment. |
| Cost | More expensive due to custom fabrication. | More affordable and less invasive. |
Pros and Cons of Dental Crowns and Fillings
Advantages of Dental Crowns
- Provides long-term protection for weakened teeth.
- Restores the shape, size, and appearance of the tooth.
- Prevents further decay and structural damage.
- Suitable for cosmetic enhancements and full-tooth restoration.
Disadvantages of Dental Crowns
- Requires removal of a significant portion of the natural tooth.
- More expensive than a filling.
- Typically requires multiple appointments unless using same-day crown technology.
Advantages of Dental Fillings
- Preserves more of the natural tooth structure.
- Less invasive and quicker to complete.
- More cost-effective than crowns.
- Composite fillings can blend seamlessly with the natural tooth.
Disadvantages of Dental Fillings
- Less durable than crowns, especially for large cavities.
- Not suitable for teeth that have extensive damage or fractures.
- May need replacement more frequently than crowns.
When Is a Crown the Better Choice?
A crown is the more suitable option when:
- The tooth has a large cavity that compromises its structural integrity.
- A filling is not sufficient to restore the tooth’s function.
- The tooth is fractured and requires reinforcement.
- A root canal has been performed, necessitating additional protection.
- A patient seeks a long-lasting solution for a damaged or misshapen tooth.
When Is a Filling the Better Choice?
A filling may be the better option if:
- The decay is minor to moderate and does not compromise the tooth’s strength.
- The patient prefers a more conservative, cost-effective treatment.
- The tooth is otherwise healthy, requiring only minor restoration.
Cost Comparison: Crowns vs. Fillings in Australia
The cost of dental restorations varies based on the material, location, and complexity of the procedure. Dental fillings typically range from $150 to $450 per tooth for composite resin, $130 to $300 for amalgam, and $400 to $1,500 for ceramic. Dental crowns are generally more expensive, with porcelain or ceramic crowns costing between $1,200 and $2,500 per tooth, zirconia crowns ranging from $1,500 to $3,000, and metal or porcelain-fused-to-metal (PFM) crowns priced at $1,200 to $2,000 per tooth. Private health insurance may cover part of the cost, depending on your policy.

Frequently Asked Questions
Can a filling be replaced with a crown?
Yes, if a filling wears down or the tooth becomes too weak, a crown may be necessary to restore its function and strength.
How long do crowns and fillings last?
Crowns typically last 10–15 years, sometimes longer with proper care. Fillings usually last 5–10 years, depending on the material used and oral hygiene habits.
Which option is better for front teeth?
For small cavities in front teeth, composite fillings work well. However, for significant damage or cosmetic concerns, a porcelain or ceramic crown provides a more aesthetic and durable solution.
Do crowns and fillings stain over time?
Composite fillings may discolour slightly over time, while porcelain and zirconia crowns are more resistant to staining. Maintaining good oral hygiene and avoiding stain-causing foods can help preserve their appearance.
Conclusion: Choosing the Right Option for Your Needs
The decision between a dental crown and a filling depends on the extent of tooth damage, long-term durability, and budget considerations. A filling is a simpler and more cost-effective option for minor cavities, while a crown offers better protection and longevity for significantly damaged or weakened teeth.
If you’re unsure which option is right for you, scheduling a dental consultation can help you make an informed decision based on your specific needs. Investing in the right treatment now can prevent future complications and help maintain a healthy, confident smile.
